Floribunda rose plant named ‘KORteidros’

ABSTRACT

A new and distinct variety of Floribunda Rose Plant, herein referred to by its cultivar name, ‘KORteidros’, is provided which forms in abundance on a substantially continuous basis attractive, medium red colored blossoms with a cream reverse. The vegetation is vigorous and the growth habit is very bushy and compact. Attractive ornamental glossy, dark green foliage is formed. The new variety is particularly well suited for providing distinctive ornamentation in the landscape.

Botanical/commercial classification:

Latin name—Rosa hybrida.

Common name—Floribunda Rose Plant.

Varietal denomination: ‘KORteidros’.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Plant Breeders' Right ApplicationNumber 2017/2303, which was filed at Community Plant Variety Office inthe European Union on Sep. 20, 2017, the contents of which are herebyincorporated by reference for all purposes.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Floribunda Rose Plant of the presentinvention was created during May 2005 at Offenseth-Sparrieshoop, Germanyby artificial pollination wherein two parents were crossed whichpreviously had been studied in the hope that they would contribute thedesired characteristics. The female parent (i.e., seed parent) of thenew variety was an unnamed seedling from a previous cross between anunnamed seedling (non-patented in the United States) and the ‘KORpeligo’variety (non-patented in the United States). The male parent (i.e.,pollen parent) of the new variety was the ‘KORfloci08’ variety (U.S.Plant Pat. No. 19,362).

The parentage can be summarized as follows:(unnamed seedling x ‘KORpeligo’) x ‘KORfloci08’

The seeds resulting from the above pollination were sown and smallplants were obtained which were physically and biologically differentfrom each other. Selective study resulted in the identification of asingle plant of the new variety.

It was found that the new Floribunda Rose Plant of the present inventionpossesses the following combination of characteristics:

-   -   (a) abundantly and substantially continuously forms attractive,        medium red colored blossoms with a cream reverse,    -   (b) exhibits a very bushy and compact growth habit,    -   (c) forms vigorous vegetation, and    -   (d) forms attractive ornamental glossy, dark green foliage.

The new variety well meets the needs of the horticultural industry. Itcan be grown to advantage as ornamentation in parks, gardens, publicareas, and in residential settings. Accordingly, the plant isparticularly well suited for growing in the landscape.

The new variety can be readily distinguished from its ancestors. Morespecifically, the (unnamed seedling x ‘KORpeligo’) variety (i.e., seedparent) exhibits a lower petal count, a less bushy growth habit, and adifferent flower color compared to the new variety. Additionally, the‘KORfloci08’ variety (i.e., pollen parent) exhibits a less roundedflower shape and less disease resistance compared to the new variety anddisplays orange-red colored flowers, whereas the new variety displaysmedium red colored flowers with a cream reverse. Moreover, the newvariety can be readily distinguished from non-parental related similarvarieties. For example, the ‘JACzotta’ variety (U.S. Plant Pat. No.12,128) displays less petals and is taller and wider compared to the newvariety.

The new variety has been found to undergo asexual propagation in KleinOffenseth-Sparrieshoop, Germany by a number of routes such as budding.Asexual propagation techniques in Germany, such as budding, have shownthat the characteristics of the new variety are homogeneous, stable, andstrictly transmissible by such asexual propagation from one generationto another. Accordingly, the new variety undergoes asexual propagationin a true-to-type manner.

The new variety has been named ‘KORteidros’.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of colors is that of The RoyalHorticultural Society (R.H.S. Colour Chart, 2015 edition). Theterminology which precedes reference to the chart has been added toindicate the corresponding color in more common terms. The descriptionis based on the observation of a three-year-old specimen of the newvariety, observed during June, while growing in a field on its own rootsat Cochranville, Pa.
